Thus, in the once celebrated question of Pope Joan, the silence of all writers near the time as to so wonderful a fact, was justly deemed a kind of _prerogative_ argument, when set in opposition to the many repetitions of the story in later ages. But the silence of Gildas and Bede as to the victories of Arthur is no such argument against their reality, because they were not under an historical obligation, or any strong motive, which would prevent their silence. Generally speaking, the more anomalous and interesting an event is, the stronger is the argument against its truth from the silence of contemporaries, on account of the propensity of mankind to believe and recount the marvellous; and the weaker is the argument from the testimony of later times for the same reason. A similar analogy holds also in jurisprudence. The principle of our law, rejecting hearsay and secondary evidence, is founded on the Baconian rule. Fifty persons may depose that they have heard of a fact or of its circumstances; but the eye-witness is the prerogative instance. It would carry us too far to develop this at length, even if I were fully prepared to do so; but this much may lead us to think, that whoever shall fill up that lamentable _desideratum_, the logic of evidence, ought to have familiarised himself with the Novum Organum. [213] “The effects which Bacon’s writings have hitherto produced, have indeed been far more conspicuous in physics than in the science of mind. Even here, however, they have been great and most important, as well as in some collateral branches of knowledge, such as natural jurisprudence, political economy, criticism and morals, which spring up from the same root, or rather which are branches of that tree of which the science of mind is the trunk.” Stewart’s Philosophical Essays, Prelim. Dissertation. The principal advantage, perhaps, of those habits of reasoning which the Baconian methods, whether learned directly or through the many disciples of that school, have a tendency to generate, is that they render men cautious and painstaking in the pursuit of truth, and therefore restrain them from deciding too soon. Nemo reperitur qui in rebus ipsis et experientia moram fecerit legitimam. These words are more frequently true of moral and political reasoners than of any others. Men apply historical or personal experience, but they apply it hastily, and without giving themselves time for either a copious or an exact induction; the great majority being too much influenced by passion, party-spirit, or vanity, or perhaps by affections morally right, but not the less dangerous in reasoning, to maintain the patient and dispassionate suspense of judgment (ακαταληψια [akatalêpsia]), which ought to be the condition of our enquiries.
